44. Byasa mukoyamai Nakae, 2015

Byasa hedistus mukoyamai Nakae, 2015; Butterflies, 70: 4, f. 1–2, 4–5; TL: Baima Xueshan, Yunnan, China.

Distribution: confined to the subalpine mountains in N.W. Yunnan.

Note: The first author collected a male specimen from Zhongdian (3,000 m), N.W. Yunnan with evident subapical white spots on the hindwing, while the genitalia agree with those illustrated in the original description of mukoyamai (Nakae 2015) . Nakae (2021) elevated the taxon to species status. Unpublished DNA data also showed its difference from B. hedistus (Jordan, 1928).
